Custom Post Type Query W/Category Dropdown

Question

You seem to be using 2 separate queries there, the first (query_posts) won’t do anything, and the second is the query that will be used. Have you tried:

$args=array(
  'category__in' => $cats,
  'post_type' => 'profiles',
  'posts_per_page' => 10,
  'order'=> 'ASC',
  'orderby' => 'title'
  );
$loop= null;
$loop = new WP_Query($args);

Try that instead of:

query_posts(array( 'category__and' => $cats ));

and

<?php $loop = new WP_Query( array( 'post_type' => 'profiles', 'posts_per_page' => 10, 'order'=> 'ASC', 'orderby' => 'title' ) ); ?>
